 ## Structure
 
+To keep the plotly.js independent of the version of this package, the generated directory contains a directory per plotly version supported. The plan is to support all minor releases and update as patches are released. But because I can not do it myself, I will accept PRs if anyone wants any specific version.
+
+Updates to the package will affect all schemas. This will be done as we improve the generator.
+
 Each trace type has its own file on **graph_objecs (grob)** package. The file contains the main structure and all the needed nested objects. Files ending with **_gen** are automatically generated files running `go generate`. This is executing the code in **generator** package to generate the structures from the plotly schema. The types are documented, but you can find more examples and extended documentation at [Plotly's documentation](https://plotly.com/python/).
 
 The values that can hold single values or arrays are defined as custom types that are a type definition of `interfaces{}`. Most common case are X and Y values. You can pass any number slice and it will work (`[]float64`,`[]int`,`[]int64`...). In case of Hovertext, you can provide a `[]string` to display a text for each point, a `string` to display the same for all or `[]int` to display a number.
